Symmetry field

Fully integrated reservoir/multi-phase gathering system simulator


Our fully integrated reservoir/multi-phase gathering system simulator enables you to quickly optimize your total field, no matter what the size.

Symmetry Field Workspace models large and small gas properties. The simulation of complex pipeline systems (with or without liquids), vertical/horizontal wells, 3D reservoirs, and simple tanks are all possible in one stand-alone model. Additional capabilities include flow splitting, line looping, parallel/series compression, multiple delivery points, and injection/withdrawal scenarios. The drag-and-drop pipeline design feature and on-screen UTM coordinate system enable the user to build surface network systems quickly and accurately.
